Connectivity in digraphs SpringerLink

WebThe theory of connectivity is extended from graphs to digraphs by introducing connectivity measures similar to the well-known point- and line-connectivities for graphs. Some simple upper and lower bounds are discussed for these parameters, and classes of digraphs are presented with various prescribed connectivities.
